Definitions

  • the invention relates generally to an adapter assembly which is connected to a housing of an electronic throttle control assembly, where the adapter assembly is suitable for connection with a pipe or conduit.
  • Electronic throttle bodies are generally known, and it is typical for a conduit to be in fluid communication with the throttle body for directing air into the throttle body, where the throttle body controls the flow of the air into an engine.
  • Typical throttle bodies are made as a single component, but certain parts that are formed as part of the throttle body are more complex, and expensive to manufacture. In some instances, it may be advantageous to form certain parts separately, and connect them during assembly. However, there are certain features of the electronic throttle body that are required for suitable operation, the functionality of which may be affected if particular parts are manufactured separately.
  • the present invention is a throttle body adapter assembly having a threaded section, with a housing of the electronic throttle control assembly receiving the threaded section.
  • the throttle body adapter assembly of the present invention provides significantly lower cost assembly, and permits single side molding during manufacturing of the throttle body adapter assembly.
  • the throttle body adapter assembly of the present invention provides alternative features for a captured seal or a void to contain excess thread sealer, and also permits a locking tab/anti-rotation feature that is indexed to the receiving element, where the screw stop angle for the adapter assembly does not have to be controlled to provide a desired orientation of the locking tab.
  • the present invention is an electronic throttle control assembly which includes a throttle body housing, a central port, the throttle body housing forming part of the central port, an upper flange section formed as part of the throttle body housing, and an adapter assembly connected to the throttle body housing.

  • a first tapered portion is formed as part of the housing portion such that the first tapered portion is adjacent the first diameter portion, and a second tapered portion is formed as part of the housing portion such that the second tapered portion is disposed between the first diameter portion and the second diameter portion.
  • a retaining surface is formed as part of the housing portion such that the retaining surface is adjacent the second tapered portion and substantially perpendicular to the second diameter portion.
  • a third diameter portion is formed as part of the housing portion, such that the third diameter portion is part of the first aperture.
  • a first threaded section is formed as part of the third diameter portion
  • a second threaded section is formed as part of the upper flange section
  • an end surface is formed as part of the third diameter portion
  • a stopper surface formed as part of the upper flange section.
  • a retention feature is integrally formed with the upper flange section, a third tapered portion is part of the retention feature, and a second retaining surface is adjacent the third tapered portion.
  • the second retaining surface is substantially parallel to the first retaining surface, such that an attachment feature of a conduit is disposed between the first retaining surface and the second retaining surface when the conduit is connected to the adapter assembly.
  • a locking tab integrally formed with the upper flange section.
  • the attachment feature is held between the first retaining surface and the second retaining surface by the locking tab.
  • the locking tab is integrally formed around the circumference of the upper flange section, and the throttle body adapter may be positioned relative to the throttle body housing independently of where the locking tab is located.
  • the throttle body housing is formed as a single component
  • the adapter assembly is formed as a single component, such that the throttle body housing and the adapter assembly do not have any joints or weld seams, further preventing leaks.
  • FIG. 1 is a perspective view of an electronic throttle control assembly having an adapter assembly, according to embodiments of the present invention
  • FIG. 2 is an exploded view of an electronic throttle control assembly having an adapter assembly, according to embodiments of the present invention
  • FIG. 3 in an enlarged view of a portion of an electronic throttle control assembly having an adapter assembly, according to embodiments of the present invention
  • FIG. 4 is a sectional side view taken along lines 4 - 4 of FIG. 1 ;
  • FIG. 5 is a sectional side view taken along lines 5 - 5 of FIG. 1 ;
  • FIG. 6 is a sectional side view of an electronic throttle control assembly having an adapter assembly, with a conduit attached to the adapter assembly, according to embodiments of the present invention.
  • FIG. 7 is a second exploded view of an exploded view of an electronic throttle control assembly having an adapter assembly, according to embodiments of the present invention.
  • the assembly 10 includes a throttle body housing 12 , and formed as part of the housing 12 is a central port, shown generally at 14 , through which air passes during operation of the assembly 10 .
  • a shaft (not shown) which extends through part of the central port 14 , where the shaft is rotatable, and mounted to the shaft is a valve plate (also not shown).
  • the shaft is mounted in a bore 16 formed as part of the housing 12 .
  • the housing 12 also includes a cavity, shown generally at 18 , and disposed in the cavity 18 is an actuator (not shown).
  • the actuator is used for controlling a gear assembly, which is then connected to the shaft, thereby controlling the position of the valve plate in the central port 14 . Changing the position of the valve plate controls the flow of air through the central port 14 .
  • the assembly 10 also includes an adapter assembly, shown generally at 20 .
  • the adapter assembly 20 includes a housing portion 22 , and formed as part of the housing portion 22 is a first aperture 24 A, which forms part of the central aperture 14 , and is of a substantially constant diameter.
  • the housing portion 22 also includes a first diameter portion 26 which is adjacent a first tapered portion 28 .
  • the housing portion 22 also has a second tapered portion 30 which is adjacent the first diameter portion 26 .
  • Adjacent the second tapered portion 30 is a first retaining surface 32 , adjacent the retaining surface 32 is a second diameter portion 34 , and adjacent the second diameter portion 34 is a third diameter portion 36 .
  • Formed as part of the third diameter portion 36 is a first threaded section 38 .
  • the first threaded section 38 is engaged with a second threaded section 40 , which is formed as part of an upper flange section 42 of the housing 12 .
  • the threaded sections 38 , 40 are both part of a connecting feature used for connecting the adapter assembly 20 to the housing 12 , however, it is within the scope of the invention that other types of connecting features may be used.
  • the upper flange section 42 includes a second aperture 24 B which is substantial alignment with the first aperture 24 A. Both apertures 24 A, 24 B make up portions of the central port 14 . Also integrally formed with the upper flange section 42 is a retention feature 44 having a third tapered portion 46 , and adjacent the third tapered portion 46 is a second retaining surface 48 .
  • the adapter assembly 20 is connected to the upper flange section 42 of the housing 12 by rotating the assembly 20 such that the first threaded section 38 engages with the second threaded section 40 .
  • the housing portion 22 is rotated until an end surface 50 of the third diameter portion 36 contacts a stopper surface 52 of the upper flange section 42 .
  • the adapter assembly 20 may be tightened as required.
  • FIGS. 6 and 7 Another feature of the present invention is a locking tab 56 integrally formed with the upper flange section 42 of the housing 12 .
  • the locking tab 56 is used when a conduit 58 , a portion of which is shown in FIGS. 6 and 7 , having a clamping feature is attached to the adapter assembly 20 and the housing 12 . Because the adapter assembly 20 is a separate component, and the locking tab 56 is formed as part of the upper flange section 42 and the housing 12 , the locking tab 56 may be formed anywhere around the circumference of the upper flange section 42 , for suitable connection with the conduit 58 as desired.

  • the conduit 58 includes some type of attachment feature, which in this embodiment is a snap-ring 60 , which may be suitable for being located between the retaining surfaces 32 , 48 when the conduit is connected to the adapter assembly 20 .
  • the snap-ring 60 may have an irregular or wave shape, or as with this embodiment, the snap-ring 60 is generally triangular in shape, and includes multiple shaft portions 66 , which flex and deflect when being placed between the retaining surfaces 32 , 48 .
  • the conduit 58 includes a shell portion, which includes both an outer shell 62 A, and an inner shell 62 B.
  • the snap-ring 60 also includes two tab features 72 , and during assembly, the tab features 72 initially contact the conduit 58 and cause the snap-ring 60 to deflect, such that as the snap-ring 60 is moved into position, the shaft portions 66 move into the apertures 64 .
  • the conduit 58 also includes a cut-out portion, or a notch 74 , which the locking tab 56 extends into when the conduit 58 is connected to the adapter assembly 20 and the housing 12 , this further facilitates a proper fit between the conduit 58 and the adapter assembly 20 .
  • the locking tab 56 may be formed anywhere around the circumference of the upper flange section 42 .
  • the conduit 58 may also be positioned relative to the adapter assembly 20 in any manner to allow the locking tab 56 to extend into the notch 74 , regardless of where around the circumference of the upper flange section 42 the locking tab 56 is located.
  • a groove 68 formed as part of the inner shell 62 B, and a seal 70 is disposed in the groove 68 , such that the seal 70 is also in contact with the first diameter portion 26 .
